Tesla Energy launched Powershare Home Backup for new Model 3 & Model Y with Powerwall 3, extending home backup by 2+ days using the car. Matthew Berman notes this largely solves battery backup's limited capacity: drive to a Supercharger, charge 30 minutes, get roughly two more days of whole-home power. He also shares how FSD restored his 83-year-old father's driving independence.
